General description

L-Arginine is an amino acid that plays a key role in many physiological processes such as tissue repair and reproduction. It is a key precursor for synthesizing nitric oxide in mammals. Due to these factors, the dietary supplementation with L-arginine may show a range of health benefits.

Application


  • Metabolomic approaches to dissect dysregulated metabolism in the progression of pre-diabetes to T2DM.: This study employs L-Arginine to examine metabolic changes during the transition from pre-diabetes to type 2 diabetes mellitus, offering new targets for early intervention (Ji et al., 2024 Jun). Link to the article.

  • Amino acid profile alteration in age-related atrial fibrillation.: Investigates the role of L-Arginine in cardiovascular aging, highlighting its potential in developing therapeutic strategies against atrial fibrillation associated with aging (Huang et al., 2024 Mar). Link to the article.

Biochem/physiol Actions

Substrate of nitric oxide synthase, which is converted to citrulline and nitric oxide (NO). Induces insulin release by a nitric oxide-dependent mechanism.
